How to test UX of v-dialog (Vuetify) components which is not appears in wrapper?

Hello, friends!

Already two weeks I’ll try to solve a little problem with vue-test-utils and testing of v-dialog component.

Aim: To test proper behaviour of UI.

Chain of Components: CreateProposal -> CreateEditProposal -> List of form fields components.

This is how tested component looks like:

My test is:

import { mount } from '@vue/test-utils'
import Vuetify from 'vuetify'
import VueRouter from 'vue-router'
import Vue from 'vue'
import CreateProposal from '../../../src/components/createProposal'
import Vuex from "vuex";
import TestHelpers from "../../test-helpers";

let wrapper
let h


Vue.config.errorHandler = (e) => { }

describe('CreateProposal Test', () => {

  const routes = [{ path: '/proposal/create', name: 'CreateProposal' }]
  const router = new VueRouter({ routes })

  const emptyProposal = {
    aimsAndScope: '',
    title: '',
    valid: false

  const dummyPerson = {
    id: 77,
    firstName: 'Joe',
    lastName: 'Dummy',
    jobTitle: 'Fake employee',
    department: 'Ghost department'

  let store = new Vuex.Store({
    modules: {
      jomPerson: {
        state: {
          data: {
            authInfo: null
        mutations: {
          setAuthInfo (state, authInfo) {
            state.authInfo = authInfo
        getters: {
          getAuthInfo (state) {
            return state.authInfo

  store.commit('setAuthInfo', dummyPerson)

  beforeEach(() => {
    wrapper = mount(CreateProposal, {
      sync: false,
      propsData: {
        proposal: emptyProposal,
        isProcessing: false
      attachToDocument: true

    h = new TestHelpers(wrapper, expect)

  it('ui rendered', async () => {
    expect(wrapper.html()).toContain('Search Responsible Editor')


I expect that after clicking a “Open Address Book” button I can check if modal window appears.

But in fact, I can’t do that because mount method does not render it.

After a days of research, I found a way to render v-dialog modal html code using render() method from ‘@vue/server-test-utils’.

import { render } from '@vue/server-test-utils'
import CreateEditProposal from '../../../src/components/createEditComponent/createEditProposal'
import CreateProposal from '../../../src/components/createProposal'
import TestHelpers from '../../test-helpers'

describe('CreateProposal UI', () => {
  let wrapper
  let h

  beforeEach(async () => {
    wrapper = await render(CreateProposal, {
      components: {CreateEditProposal}

    h = new TestHelpers(wrapper, expect)

  it('is rendered all elements correctly', () => {
    h.see('Responsible Editor')
    h.see('Open Address Book')
    h.see('>0 / 256<')
    h.see('Search Responsible Editor')


The result HTML contains all I want:

But this wrapper is not a VUE instance. So I cant interact with it with vue-test-utils.

So. Question is:
How to test UI and UX with vue-test-utils and especially with vuetify v-dialog component.

Thanks for any help!

So, friendly and attentive VUE community is not so… I see.

So, anyway, problem is in .html() that not renders dynamic tags.

How to test modal windows is appear or not:

await wrapper.vm.$nextTick()

did you ever find out an answer to this?
